4 Important safety instructions

Important safety instructions

Your projector is designed and tested to meet the latest standards for safety of information

technology equipment. However, to ensure safe use of this product, it is important that you

follow the instructions mentioned in this manual and marked on the product.

1. Please read this manual before you

operate your projector. Save it for future

reference.

2. Do not look straight at the projector lens

during operation. The intense light beam

may damage your eyes.

3. Refer servicing to qualified service

personnel.

4. Always open the lens shutter (if any) or

remove the lens cap (if any) when the

projector light source is on.

5. The light source becomes extremely hot

during operation.

6. In some countries, the line voltage is NOT

stable. This projector is designed to

operate safely within a mains voltage

between 100 to 240 volts AC, but could

fail if power cuts or surges of ±10 volts

occur. In areas where the mains voltage

may fluctuate or cut out, it is

recommended that you connect your

projector through a power stabilizer,

surge protector or uninterruptible power

supply (UPS).

7. Do not block the projection lens with any

objects when the projector is under

operation as this could cause the objects

to become heated and deformed or even

cause a fire. To temporarily turn off the

light source, use the blank function.

8. Do not operate light sources beyond the

rated light source life.

5Important safety instructions

9. Do not place this product on an unstable

cart, stand, or table. The product may fall,

sustaining serious damage.

10. Do not attempt to disassemble this

projector. There are dangerous high

voltages inside which may cause death if

you should come into contact with live

parts.

Under no circumstances should you ever

undo or remove any other covers. Refer

servicing only to suitably qualified

professional service personnel.

11. Do not block the ventilation holes.

- Do not place this projector on a blanket, bedding

or any other soft surface.

- Do not cover this projector with a cloth or any

other item.

- Do not place inflammables near the projector.

If the ventilation holes are seriously

obstructed, overheating inside the

projector may result in a fire.

12. Always place the projector on a level,

horizontal surface during operation.

- Do not use if tilted at an angle of more than 10

degrees left to right, nor at angle of more than 15

degrees front to back. Using the projector when it

is not fully horizontal may cause a malfunction

of, or damage to, the light source.

13. Do not stand the projector on end

vertically. Doing so may cause the

projector to fall over, causing injury or

resulting in damage to the projector.

14. Do not step on the projector or place any

objects upon it. Besides probable physical

damage to the projector, doing so may

result in accidents and possible injury.

15. When the projector is under operation,

you may sense some heated air and odor

from its ventilation grill. It is a normal

phenomenon and not a product defect.

6 Important safety instructions

16. Do not place liquids near or on the

projector. Liquids spilled into the projector

may cause it to fail. If the projector does

become wet, disconnect it from the power

supply's power outlet and call BenQ to

have the projector serviced.

17. This product is capable of displaying

inverted images for ceiling/wall mount

installation.

18. This apparatus must be earthed.

19. Do not place this projector in any of the

following environments.

- Space that is poorly ventilated or confined. Allow

at least 50 cm clearance from walls and free flow

of air around the projector.

- Locations where temperatures may become

excessively high, such as the inside of a car with

all windows rolled up.

- Locations where excessive humidity, dust, or

cigarette smoke may contaminate optical

components, shorten the projector's life span and

darken the image.

- Locations near fire alarms

- Locations with an ambient temperature above

40°C / 104°F

- Locations where the altitudes are higher than

3000 m (10000 feet).

Risk Group 2

1. According to the classification of photobiological safety of light sources and light source

systems, this product is Risk Group 2, IEC 62471-5:2015.

2. Possibly hazardous optical radiation emitted from this product.

3. Do not stare at operating light source. May be harmful to the eyes.

4. As with any bright source, do not stare into the direct beam.

To avoid damaging the DLP chips, never aim a high-power laser beam into the projection lens.
